SH EET-METAL CAN,

To all whom it may concern.- Be it, known'that I, HERMAN MILLER, a citizen of the United States, residing in the city'and county of New York, in the State of New York, have invented a new and useful Improvement in Sheet-Metal Cans and other Vessels, of whigh the following is a specification, reference beinghad to the accompanying drawings.

ing to my invention.

This invention is more especially intended for cans for holding and transportation of refined petroleum; and its object is to provide ajoint which in'the process of soldering by dipping into molten solder will not fail to re v ceive the solder between all the contiguous surfaces of those parts of the sheet metal of which the joint is formed. 7

The invention consists in the novel construction of the jointhereinafter described and claimed, whereby the desired result is ob tained.

Figure l in the drawings is-a vertical sectional view of a can having the joints between its sides and bottom constructed accord- Fig. 2 is a vertical section, on a greatly enlarged scale, of those partsof one of the side plates and one of the heads of a can which form the joint, illustrating the act of dipping the joint in molten solder. 7

Similar letters of reference designate corre A designates the side plates of the can, an

, B the heads thereof. The side plates, A, have their upper andlower marginal portions which unite with the heads ]3 doubled by being V folded outward, as shown at a. The heads have their marginal portions turned outward, as shown at b, and folded backward, as shown at 0, the edge of the part a being presented at the outside of the joint, the space within the outwardly turned and folded parts I) 0 being, wide enough to receive within it the folded marginal part of A; The plates being thus folded,and the'folded marginal portion of the plate A being placed within the folded marginal portion of the plate B, the parts may be sented at the outside ofthe SPBCIPICATIONforming part of Letters Patent No. 377,495, dated February 7, 1888.

Application filed December 10. 1887. Serial No. 257,507. (No model.) i I r I soldered by dipping into molten solder in the manner commonly practiced in the soldering of joints of sheet-metal cans forpetroleum, as illustrated in Fig. 2,wherein-the molten solder dipped so that the outer edges of theparts a a are submerged, two openings, dc, Fig. 2, are

presented forthe entrance of the solder'into the joint, the openingd' leadingto. the ill-- terior of the fold a, and the openinge'tothe space between a and c, and from the latter j space the solder flows freely past the bend at the bottom of the-fold a and into the, space f,

between the part b of the head andcontiguous portions of the side plate. The solder there fore fills all'the interstices between the contiguous parts of the sheet metal and makes a i very solid joint. 7

This joint possesses the same advantage as that which is the subject of my United States Patent N 0. 368,348, dated August 16,1887, so

faras'consists in there being no raw or out w edge for the solder to pass inside of the joint,

and it possesses, owing to the outward fold a i and opening d, the additional advantage of provision for the solder to enter the space withinthe fold a, which itcannot do when the 7 side plate is folded inward, as shown in that patent.

What I claim asniy invention, and desire to secure by Letters Patent, is- A soldered joint for'the plates] of a sheetmetal vessel in which both plates have their marginal portions folded, and the folded portion of one is placed within that of the other,

and inwhich the edges of both plates are preas herein described. l a
